Apple Computer wants to have $2.1 billion
available 5 years from now to fi nance production
of a handheld “electronic brain” that, based
on your behavior, will learn how to control
nearly all the electronic devices in your home,
such as the thermostat, coffee pot, TV, and
sprinkler system. The company expects to set
aside uniformly increasing amounts of money
each year to meet its goal. If the amount set
aside at the end of year 1 is $50 million, how
much will the constant increase G have to be
each year? Assume the investment account
grows at a rate of 18% per year.
